Convert all your audio files into one format for hassle-free playback on any MP3 player.

MP3 players are still the weapon of choice for music lovers across the globe thanks to their convenience, but with so many different sources of music online it can be hard to get all the newest tunes into the correct format for your device.

Freemake Audio Converter solves this conundrum. The freeware converter allows anyone to convert audio files between 40 different formats including WMA to MP3, MP3 to M4A, WAV to MP3, FLAC to MP3, AAC to MP3 and numerous others.

Files downloaded from the internet onto your computer are added to the program’s main window where the file type is identified alongside each track. At the bottom of the window there are icons that show you the different formats that tracks can be converted into, and clicking each one gives you the chance to change the quality of the track and identify where you want it to be saved. You then click 'convert' and it will transform any files that were highlighted for conversion.

Apple iOS device owners can optimise audio files for the specific M4A format preferred by Apple by clicking the relevant icon. It means iPhone, iPad, iPod, Apple TV and Mac owners can convert audio files into the best format for use with their machines.
